Your IBM Rational xde j2ee Questions, Answered

The 000-644 exam, officially titled Rational xde j2ee, is the qualifying test for the IBM Certified Solution Developer - Rational XDE for J2EE certification from IBM, a credential at the Professional level. Passing it proves you have the skills employers look for in certified professionals, and it can also support progress toward related credentials such as IBM Certifications II.

The IBM Rational xde j2ee exam gives you 90 minutes to work through 90-105 questions. That is a steady pace with little room for second-guessing, so train yourself to read each question once, flag the difficult ones, and keep moving. Before exam day, sit at least two full timed sessions in the Fast2test test engine — when the clock feels familiar, it stops being a threat.

You need 65% to pass, and the official registration fee is $150 USD. Fall short and you pay that fee in full again for every retake, which makes solid preparation the cheaper option by far. Work through the Fast2test practice questions until you score comfortably above the passing mark, then book your seat.

Basic knowledge of Java, J2EE architecture, and UML modeling Eligibility rules can change over time, so before you register, confirm the latest requirements on the official exam page: IBM 000-644 exam overview.
